Tellor

Tellor was founded in 2019 by a team based in the United States, comprising Brenda Loya, Nick Fett, and Michael Zemrose. The goal of the founders was to address the oracle problem on the Ethereum blockchain. The Tellor network is secured through its native token, Tributes (TRB). This token is used to connect and align the various participants in the Tellor ecosystem, including the data reporters, the oracle users, and the community governance.

Tellor has a few unique features that set it apart from other oracle solutions. Firstly, the process of becoming a data reporter is completely permissionless - anyone can participate by running the open-source software, without any verification or approval process. Secondly, Tellor's oracle allows data to be submitted in a flexible, byte-based format, making it suitable for a wide range of blockchain applications. Finally, Tellor uses a dispute mechanism and token staking to incentivize accurate data reporting and disincentivize bad actors, helping to secure the network.

The Tellor network is secured through the use of its native token, Tributes (TRB). Data reporters must stake TRB in order to submit data, and this stake can be slashed if the network determines that the data is incorrect. This dispute mechanism, along with the community governance of the Tellor protocol, helps to maintain the integrity and security of the data being reported.
